Decent but missing components
Response from developer
Dear Amhariclearner, If you would allow us a belated response, you might be pleased to know that those features are hiding in plain sight! The Letter puzzle is available when you are studying the letters. Tap on the right arrow > when you are in the Alphabet screen. Once you are in the letter view, proceed to tap on the action button on the top right of the screen. Voila! You find the letter puzzle. The flash cards are available in the Vocabulary section. Once you are there, tap on the upward action arrow, and, Voila! the flash cards are at your service. Do feel free to explore these and other feature and drop us a line if you have questions, comments or suggestions.
